    Participating in BETA Exams

    A critical part of the exam development process is the beta exam. By taking the exam in its beta format, candidates provide us with useful information to evaluate the technical accuracy, relevance, and psychometric characteristics of the questions before we score examinees.

    Get 80% off the DNSC beta exam. If you take the beta exam, Knowledge Pillars will send a 25% discount voucher to the same email that you use to register for exams AFTER the beta exam has been scored. You can apply that voucher to your next Knowledge Pillars exam registration. 

    Note Participation in the beta is on a first come, first served basis. Due to popular demand, we recommend that you register as soon as the beta registration period begins. 

    Candidates located in China, India, Pakistan, or Turkey are not eligible to participate in beta exams for security reasons.

    Preparing for a beta exam

    You will have access to the Exam Details page that lists the skills that will be assessed on the exam. Knowledge Pillars does not currently offer training materials for its exams.

    People interested in beta exams usually have access to other resources, are experienced with the technology, or work with the beta product. We recommend that you consult peers, community resources, and early-adopter articles for support if you need additional preparation materials.

    Beta exam scoring and results

    When you complete a beta exam, you do not receive a score immediately because the scoring model for the exam is not yet finalized.

    You usually receive your exam score within 2-3 weeks after the exam becomes available worldwide—this can be up to 16 weeks after you take the exam, depending on when in the beta period you took the exam. This time frame reflects the comprehensive process used to evaluate the beta exam results, including statistically analyzing the data to evaluate the performance of each question and reading and evaluating all comments provided during the beta exam. The rescore process starts on the day that exams go live, and final scores are released approximately 10 days later.

    Note Participation in beta exams is voluntary, and Knowledge Pillars makes no promises or guarantees regarding the beta exam process, availability of your scores, or the timing of your results. Generally online proctored exam results are presented within 72 hours.

    Passing the beta exam

    Passing a beta exam in your certification exam counts toward your transcript. You do not need to retake the exam in its final version and you will receive a digital badge as confirmation of your passing score. Make sure that you take another exam within a year so you can take advantage of the 25% discount you earned for taking the beta exam through our beta exam discount program.

    If you do not pass the beta exam, you cannot retake the beta exam. If you are interested in earning a certification that requires successful completion of that exam, you must wait to retake the exam at regular cost when it’s live, or you can apply the 25% discount that you received for taking the beta exam through our beta exam discount program.

    I am excited about this .Net certification exam. This exam will give me the opportunity to align, improve and validate my skills as a developer. Some of my recent colleagues even argued that having a certification like this provided great conversation mechanisms during their interviews with potential employers. These certifications are really a great place to start if you’re looking to apply for an entry level job or just wanting to prove that you have the capabilities to perform front-end development tasks.
